RECONSTRUCTION METHOD OF DISCRETE DIGITAL SIGNALS IN NOISY OVERLOADED WIRELESS COMMUNICATION SYSTEMS
A computer-implemented reconstruction method of discrete digital signals in noisy overloaded wireless communication systems that is characterized by a channel matrix of complex coefficients, the method including, receiving the signal from channel by a signal detector, measuring the noise power by a noise power estimator at the receiver, forwarding the detected signal and noise power estimation to a decoder that estimates the transmitted symbol, wherein the estimation of the decoder produces a symbol that could probably have been transmitted it is forwarded to a de-mapper, which outputs the bit estimates corresponding to the estimated transmit signal and the corresponding estimated symbol to a microprocessor for further processing.
Brake-by-wire braking system having at least one brake circuit, method for operating the braking system and diagnosis valve for a braking system of this type
To check the functionality/leak-tightness of a brake-by-wire brake system, a motor-operated brake pressure transducer is actuated. In this case, a pressure medium would flow out into a reservoir via a master brake cylinder. A diagnostic valve is therefore provided between the master brake cylinder and the reservoir, which diagnostic valve is composed of a check valve and a restrictor connected in parallel with respect to the check valve. The outflow of pressure medium is limited by the restrictor. Because the gradient of the pressure dissipation can be calculated, a measured pressure build-up can be compared with that which is to be expected, and a determination of functionality/leak-tightness can be derived from the comparison.
